【Car owner's car knowledge】In the cold winter, how to maintain the car in winter has become a topic of concern for car owners. After the vehicle has passed the warranty period, some failures will inevitably occur. Cars need "three points of repair and seven points of maintenance", that is, through active inspection and maintenance, to find and eliminate some initial, potential, and hidden faults.
cooling system
In winter, it is necessary to regularly check whether the water tank, water pump and belt, water pipe, water replenishment tank and other components are working properly. If there is any damage or failure, it is best to repair or replace it in time. Otherwise, a bucket of antifreeze may be wasted for a small water pipe. In particular, the water temperature of some cars is too high in summer, and the repairers remove the thermostat. Although the problem in summer can be solved, it will be reversed in winter.
warm air
It is best to test whether there is hot air, whether there is abnormal noise in the fan operation, and whether the air duct is unobstructed. The problem sometimes encountered is that the antifreeze in the warm air water pipe does not flow for a long time, and the condensation blocks the circulation pipeline. Although it does not affect the driving, it is very troublesome to maintain.
antifreeze
Many drivers generally do not have the habit of checking antifreeze, but when driving to the north, they should pay attention. Check for lack of liquid and deterioration, and if necessary, replenish or replace it in time. Antifreeze seems to be a trivial matter, but it has a great impact on the car, ranging from blocking the pipeline to corrosion and damage to the cylinder. So choose and use antifreeze carefully, one is not to mix it, and the other is not to use fake and shoddy products. In addition, in general, antifreeze should be replaced every two years, and it is best to rinse the cooling system with clean water before replacement.
engine oil
Check whether the label is cold, missing or deteriorated. In winter, the oil in the cold car is too thick, which will affect the starting and increase the wear of the parts. At the same time, the hot car oil is too thin, which will reduce the lubrication and sealing performance. To choose a high-quality compound oil suitable for winter. If it's at or near the required oil change time, it's best to change it before it gets colder.
windshield
Keeping the windshield clear is the basic condition for safe driving. The wipers should be wiped regularly in winter, and the windshield can be wiped clean in rainy days. In addition, some windshield deicer can be added to the glass water. When the windshield is frozen, spray the glass water on it, and the ice will melt, unlike ordinary glass water, which is more troublesome when it freezes.
body
Before winter, it is best to add a layer of protective film to the car body. Car paint coating or mirror glaze containing Teflon polymer can resist the erosion of acid rain and fog. When driving to the northern region, salt water is sprinkled on the road after snowfall, and the salt water splashed on the car body is very harmful to the car paint, so pay attention to cleaning.
chassis
In winter, the chassis of the car is always in direct contact with the rain, and it is easy to rust, and the speeding tires will throw the muddy water on the chassis of the car. After the rain and the weather, the chassis of the car began to rust. Therefore, it is best to take some time before winter and give the chassis a rust-proof care.
battery
The battery is most afraid of low temperature, and the battery capacity in a low temperature environment is much lower than that at room temperature. Therefore, before the cold season comes, the electrolyte of the battery should be supplemented and the specific gravity of the electrolyte should be adjusted. At the same time, clean the terminals of the battery and apply special grease to protect it to ensure reliable starting and prolong battery life. If the vehicle is parked in the open air or in a cold storage for several weeks, the battery should be removed and stored in a warmer room to prevent damage to the battery from freezing.
tire
The tire rubber will become hard and relatively brittle in winter, and the coefficient of friction will decrease, so the tire pressure should not be too high, but it should not be too low. Low outside air temperature, low tire pressure, and serious soft tires can accelerate aging. In winter, it is necessary to clean the inclusions in the tread frequently, try to avoid using tires that have been repaired more than once, and replace tires with greater wear and different brands and different patterns. The wear of tires inside and outside is very different. In order to ensure safety and reduce wear and tear, the tires should be replaced regularly.
